Quick Vegan Portobello Pizza
Using a large tortilla as a pizza crust makes this Quick Vegan Portobello Pizza recipe a snap to prepare. For gluten-free pizza, use a gluten-free tortilla.

Tortillas make great pizza crusts. The trick is to use a pizza screen so the crust becomes nice and crispy. You won’t believe how fast you can throw a pizza together—including this Quick Vegan Portobello Pizza.
A Few Make Ahead Ingredients
This simple recipe requires just a few ingredients:
- Large tortilla
- Vegan Parmesan Hummus
- Arugula
- Onion
- Portobello mushrooms
- Kalamata olives
- Vegan “Parmesan Cheese”
It’s especially quick and easy if you make the hummus and “cheese” ahead of time.
The vegan “Parmesan cheese”—or what my family calls “shaker cheese”—is easy to make yourself. Here are a couple of ways to do it.
Vegan “Parmesan Cheese”
I often use a recipe I found on Minimalist Baker. It’s super easy. You just blend the following ingredients together until they become fine crumbs:
- ¾ cup raw cashews
- 3 tbsp nutritional yeast
- ¼ tsp garlic powder
- ¾ tsp Himalayan cooking salt
Vegan “Parmesan Cheese” – without Nutritional Yeast
Some people need to avoid nutritional yeast. If you are one of them, try blending these ingredients together instead:
- ½ cup Brazil nuts or cashews
- ½ teaspoon Himalayan cooking salt
- ½ teaspoon dried basil
- 2 cloves of garlic
The fresh raw garlic in the second option provides an extra kick! Feel free to adjust the measurements to find the ratio you like best.

As soon as I developed the Vegan Parmesan Hummus recipe, I knew it would make a great pizza topping. The cheesy, garlicky flavor more than satisfies. It also pairs nicely with the earthy taste of Portobello mushrooms and peppery arugula.
